Aspects of the present disclosure relate to mapping content delivery. A client device provides, to a map management server, a request for a map of a geographic region. The client device receives, from the map management server, an identification of tiles for the map. The client device provides, to a first tile server, a request for the tiles for the map. In response to receiving the tiles from the first tile server: the client device displays the map of the geographic region based on the tiles.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method implemented at a client device, the method comprising: providing, to a map management server and from the client device, a request for a map of a geographic region; receiving, from the map management server in response to the request for the map, an identification of tiles for the map; providing, to a first tile server and from the client device, a request for the tiles for the map; in response to receiving the tiles from the first tile server: providing for display, at the client device, of the map of the geographic region based on the tiles; and in response to failing to receive the tiles from the first tile server: providing a plurality of requests for the tiles for the map, each request from the plurality of request being directed to one of a plurality of tile servers; receiving, from a second tile server from among the plurality of tile servers, an indication that the second tile server is capable of providing the tiles for the map; cancelling, in response to the indication from the second tile server, the request for the tiles from each other tile server in the plurality of tile servers; receiving the tiles from the second tile server; and providing for display, at the client device, of the map of the geographic region based on the tiles.
2. The method of claim 1 , wherein failing to receive the tiles from the first tile server comprises receiving a failure message from the first tile server.
3. The method of claim 1 , wherein failing to receive the tiles from the first tile server comprises failing to receive a response to the request to the first tile server during a threshold time period after providing the request to the first tile server.
4. The method of claim 1 , further comprising: selecting the first tile server from a set of tile servers based on a geographic distance between the client device and the first tile server being less than a geographic distance between the client device and each other tile server from among the set of tile servers.
5. The method of claim 4 , wherein the set of tile servers comprises the first tile server and the plurality of tile servers.
6. The method of claim 1 , wherein each tile from among the tiles tile stores a portion of the map at a given zoom level as an image taking up a predefined area measured in pixels.
7. The method of claim 1 , wherein each of the plurality of tile servers stores geographic information for a different geographic area.
8. A non-transitory machine-readable medium storing instruction which, when executed by one or more processors of a client device, cause the client device to implement operations comprising: providing, to a map management server and from the client device, a request for a map of a geographic region; receiving, from the map management server in response to the request for the map, an identification of tiles for the map; providing, to a first tile server and from the client device, a request for the tiles for the map; in response to receiving the tiles from the first tile server: providing for display, at the client device, of the map of the geographic region based on the tiles; and in response to failing to receive the tiles from the first tile server: providing a plurality of requests for the tiles for the map, each request from the plurality of request being directed to one of a plurality of tile servers; receiving, from a second tile server from among the plurality of tile servers, an indication that the second tile server is capable of providing the tiles for the map; cancelling, in response to the indication from the second tile server, the request for the tiles from each other tile server in the plurality of tile servers; receiving the tiles from the second tile server; and providing for display, at the client device, of the map of the geographic region based on the tiles.
9. The machine-readable medium of claim 8 , wherein failing to receive the tiles from the first tile server comprises receiving a failure message from the first tile server.
10. The machine-readable medium of claim 8 , wherein failing to receive the tiles from the first tile server comprises failing to receive a response to the request to the first tile server during a threshold time period after providing the request to the first tile server.
11. The machine-readable medium of claim 8 , the operations further comprising: selecting the first tile server from a set of tile servers based on a geographic distance between the client device and the first tile server being less than a geographic distance between the client device and each other tile server from among the set of tile servers.
12. The machine-readable medium of claim 11 , wherein the set of tile servers comprises the first tile server and the plurality of tile servers.
13. The machine-readable medium of claim 8 , wherein each tile from among the tiles tile stores a portion of the map at a given zoom level as an image taking up a predefined area measured in pixels.
14. The machine-readable medium of claim 8 , wherein each of the plurality of tile servers stores geographic information for a different geographic area.
15. A client device comprising: one or more processors; and a memory storing instruction which, when executed by the one or more processors, cause the client device to implement operations comprising: providing, to a map management server and from the client device, a request for a map of a geographic region; receiving, from the map management server in response to the request for the map, an identification of tiles for the map; providing, to a first tile server and from the client device, a request for the tiles for the map; in response to receiving the tiles from the first tile server: providing for display, at the client device, of the map of the geographic region based on the tiles; and in response to failing to receive the tiles from the first tile server: providing a plurality of requests for the tiles for the map, each request from the plurality of request being directed to one of a plurality of tile servers: receiving, from a second tile server from among the plurality of tile servers, an indication that the second tile server is capable of providing the tiles for the map; cancelling, in response to the indication from the second tile server, the request for the tiles from each other tile server in the plurality of tile servers; receiving the tiles from the second tile server; and providing for display, at the client device, of the map of the geographic region based on the tiles.
16. The client device of claim 15 , wherein failing to receive the tiles from the first tile server comprises receiving a failure message from the first tile server.
17. The client device of claim 15 , wherein failing to receive the tiles from the first tile server comprises failing to receive a response to the request to the first tile server during a threshold time period after providing the request to the first tile server.
